The correct answer is B.
B. The change in momentum suffered by the lead ball is less than that of the rubber ball.
This is because rubber balls are highly elastic, and when they strike a surface, they can deform and quickly regain their original shape, which causes them to bounce back.
On the other hand, lead balls are not very elastic, and when they strike a surface, they deform significantly and lose more of their initial momentum as heat and sound energy. Thus, the change in momentum suffered by the lead ball is less than that of the rubber ball.

The correct option is B.
Because of rubber ball momentum 2mv.
And lead ball mv.
Because of rubber ball momentum 2mv.
And lead ball mv.

The correct answer is option B. Because momentum change is more in rubber ball then lead ball.
